|Size||SD1 provides sanitary and storm water sewer services for an area of 220 square miles, including 30 municipalities and the unincorporated areas of the three Northern Kentucky counties of Boone, Kenton and Campbell. SD1′s sanitary system is composed of 1,650 miles of sanitary and combined sewers, seven miles of twelve-foot-diameter conveyance tunnel, 142 pump stations, 15 flood stations, 3 major treatment plants and 8 small package treatment plants. Dry Creek Wastewater Treatment Plant treats an average of 33 million gallons per day. Eastern Regional Water Reclamation Facility treats an average of 1 million gallon per day. Western Regional Water Reclamation Facility was built in anticipation of population growth and development in Boone County, and is projected to treat 3 million gallons per day when it opens in May of 2012. Western Regional will have a maximum capacity of 20 million gallons per day. SD1 also owns and maintains approximately 400 miles of separate storm sewers in the region.|
|Process Train||SD1′s three wastewater treatment plants utilize state-of-the-art treatment and odor-control technologies, including ultraviolet (UV) light for disinfection and biofilter mulch pits to minimize odors. Wastewater entering SD1′s treatment plants undergoes a series of steps to clean and disinfect the water before it is released back into the environment, including: Headworks monitoring of hydrogen sulfide; chlorination with sodium hypochlorite; screening for debris; grit removal; separation of solids in settling tanks; removal of solids, fats, oils and grease; digestion of organic material by bactera in aeration tanks; a second chlorination for disinfection in clarifiers; dechlorination for environmenatl safety; and UV treatment (at Eastern & Western Regional facilities). Approximately 360 tons of bio-solids per day are dewatered in centrifuges and taken to a landfill.|
|Type of Discharge||Wastewater from separate sanitary and combined sewers is discharged into the Ohio River after intense treatment at one of SD1′s three treatment plants. Water in SD1′s storm sewers discharge into local Northern Kentucky waterways, including ponds, lakes, creeks, streams and rivers.|
|Lab Facility Availability||The laboratory at Dry Creek Wastewater Treatment Plant analyzes nearly 50,000 samples of incoming and outgoing wastewater, as well as samples from local waterways and industrial plants each year. Mandatory tests of dissolved oxygen, pH, fecal coliform and many others are required by the EPA.|
|Other||Adaptive Watershed Management Approach
SD1′s Consent Decree is the country’s first enforcement action that allows a community to use the watershed management approach to more efficiently and cost-effectively meet federal Clean Water Act requirements for addressing CSOs and SSOs. This approach is based on the fact that sewer overflows are not the sole source of impairment for Northern Kentucky’s streams and rivers. Traditionally, most Consent Decrees focus solely on CSOs and SSOs, with an emphasis on gray infrastructure solutions. SD1′s watershed approach identifies the characteristics of individual watersheds and considers CSOs and SSOs along with other sources impacting the waterways (such as runoff and dry weather sources). Additionally, there is an iterative five-year permit review cycle that allows time to investigate new technologies and update the full system plan, using information gained from the implementation of projects during previous years. SD1′s watershed approach:
• Recognizes non-point sources of pollution and their relative impacts, and puts CSOs and SSOs into context with those sources.
• Provides a process to address and control highest regional priorities first to offset controls on CSOs.
• Uses an integrated approach of controls that will address both wet and dry weather sources of pollution and lead to a greater improvement in water quality and public health.
• Provides additional benefits to the community such as air quality, wildlife habitat, urban beautification and economic development.
• Directs funds to projects that provide the greatest benefits.
